how to replace windshield washer pump motor?

Recommended Posts

Just purchased a replacement pump motor, as the original motor is too weak to spray fluid anymore, even after replacing the tubing.  How does the old motor come out of its rubber holder?  Been dripping penetrating oil around the motor.  Does the rubber holder need to be removed from the fluid reservoir first?  The rubber isn't very pliable.

Searched the forums repeatedly, found lots of posts about purchasing a replacement motor, no advice found on how to physically remove/replace it.  Maybe I didn't use the correct search terms.

I've been using this forum a lot since buying a 71 and 72 240z this year, everyone has been super helpful.  Thanks!

I replaced my pump motor last year.  If I remember correctly, I removed the rubber holder and pump motor together as a unit, and then separated them afterwards.

With the hot water soak and two pry bars (which mysteriously look like screw drivers) was able to separate the reservoir from the rubber/motor assembly.  Now, how to extract the motor from its hard rubber housing?  The motor is going to be discarded, so destroying it while using a press to extract it seems reasonable.  Is there another option?

After soaking the whole thing in hot water I tried to get some dish washing liquid between the rubber and motor, see if you can get a small thin screw driver or awl between them all the way around. The ones I've worked on had a layer of corroded aluminum that sticks to the rubber.

With enough heat and squirting with penetrant, got the old weak motor out of the rubber housing, after extracting the rubber housing from the reservoir.  First installed the new MSA motor into the rubber housing, then tried to install that assembly onto the reservoir; not possible.  Removed the motor, installed the rubber housing onto the reservoir, THEN pushed the motor into the housing.  Success.

Need to re-align the metal squirt tubes so the washer fluid sprays through the valence slots.  Also need a tiny hose clamp (or maybe safety wire) for the passenger side washer fluid tubing (new tubing), so all the fluid sprays into the squirt tubes instead of soaking the firewall.

Thanks for all the suggestions!

And on Amazon.ca, $5.88 CAD with one wrong connector... If you want I'll change the one wrong connector and only charge you $20. CAD.
